リモート アクセスが有効になっている CFC ファイルがあり、これを使用して、データベースからの画像レコードの追加/削除などのさまざまな管理タスクを実行しています。この CFC への呼び出しは、管理ページのカスタム JavaScript を介して AJAX を介して行われます。セキュリティで保護されていると思われるディレクトリに CFC を配置しましたが、画像が勝手に消えるという問題があり、まったく安全ではないことがわかりました。
CFCを確保したい。管理ページに使用するセッション ベースのセキュリティ CFC が既にあり、管理ページの 1 つが要求されるたびに保護メソッドが呼び出され、認証が失敗した場合にユーザーがリダイレクトされます。CFC でこれを使用できますか? もしそうなら、それを実装する最良の方法は何ですか? そうでない場合、どのようにセキュリティを実装する必要がありますか?
以下は私のCFCの例です:
